#21 in my book: When female friend, acquaintance or colleague complains about experiencing cat-calling or sexual harassment, inform her that she's "gonna miss it" when she's old and no longer attractive or desirable.Bonus points if you tell her "it won't last much longer" because of the rate at which she's ageing/letting herself go.

#14 is just wrong. It has always been to women's evolutionary advantage to have many men having a vested interest in helping raise their children, not just one. A significant number of hunter gatherer societies have women in relationships with multiple men who in turn all help with childrearing. Some of these cultures even believe that one man alone cannot possibly father a child, that it takes several, and that the more there are the stronger the child will be. So this one is not male-chauvinist, it is just scientifically wrong.

Chauvinists and racists of every ilk love relying on pseudo-science 9and dumping on actual science) in support of their warped beliefs.

My Cornell students were shocked to discover that "the black people are not in any way different from us besides the color of their skin. Like, they don't have any special capacities or don't think and feel in a different way. Are you sure about that, professor?"

I can add #22 If your female colleague or a friend isn't in her 20ies anymore, mention the new wonderful cosmetic treatments you've heard of. For extra points, tell about a female acquaintance, who "takes care of herself" and "after using Botox every X years, looks just great!"

RE 5 - but what if she is thin? ;) Talking about Anorexia just doesn't do it in our society. Just recently I read an article about how people love tut-tutting about Anorexia, but in practice the culture promotes and rewards it. F.e. by giving modeling jobs.

"I’m running an experiment in which I plan to cook 100 meals from cookbooks published by excellent chefs in one year and blog each one of them. I hope to also write about my personal history with food and cooking, as well as what I learn along the way."

I read over this list and started to laugh . . . and then it dawned on me- I have been the recipient of most of these comments (1 with bp, 2 w/bp, 4 w/bp, 5, 6- from a potential employer at a job interview!, 7 w/bp, 8, 9 w/bp, 10 w/bp, 12, 13 w/bp, 14, 15 w/bp, 16 w/bp, 17 w/bp, 19, 20 w/bp, 21 w/bp). That's when it wasn't funny anymore. At all.
